Picture this: you wake up one morning, check your investment portfolio, and see that the value has plummeted by thousands or even lakhs of rupees overnight. This isn’t just a bad dream––it’s the reality many investors have faced during stock market crashes.
In India, such events have not only erased personal wealth but have also sent shockwaves through the entire economy. But stock market crashes are more than just sudden drops in numbers; they reveal underlying weaknesses in the financial system and can have long-lasting effects on businesses, jobs, and everyday life.

Stock market crash definition
A stock market crash is a rapid and severe decline in stock prices across a significant portion of the market, resulting in a substantial loss of wealth. Unlike regular market corrections, which are more gradual and less dramatic, crashes are marked by their speed and intensity––often seeing major indices fall by more than 10% within a matter of days.
The reasons behind stock market crashes are usually a mix of economic shocks, panic selling, and herd mentality, where fear spreads quickly among investors and triggers mass sell-offs. Though rare, crashes can have far-reaching consequences, impacting everything from corporate profits to employment and consumer confidence.

What causes a stock market crash?
1. Speculation
Speculation occurs when investors buy stocks with the hope of selling them at higher prices, often without considering the actual value of the company. When speculation becomes widespread, it can push asset prices far above their real worth, creating a bubble. Eventually, reality catches up––perhaps due to disappointing earnings, regulatory changes, or an external shock––and the bubble bursts, causing prices to crash. One of the most infamous examples in India involved market manipulation by Harshad Mehta that led to a dramatic collapse way back in 1992.
2. Rates of inflation
High inflation erodes the purchasing power of money, making everyday goods and services more expensive. To combat inflation, central banks often raise interest rates, which increases borrowing costs for companies and consumers alike. Higher rates can squeeze corporate profits and dampen investor enthusiasm, leading to widespread selling. Persistent inflation also shakes investor confidence, making markets more vulnerable to sharp declines.
3. Tax changes
Sudden changes in tax policy, such as increases in capital gains tax or the introduction of new transaction taxes, can quickly alter investor behavior. If investors expect lower post-tax returns, they may rush to sell their holdings, triggering a broader market decline. Policy uncertainty, especially around elections or major budget announcements, can amplify this effect.
Interaction of bull market, bear market, and stock market bubbles
To truly understand why crashes happen, you need to see how bull markets, bear markets, and stock market bubbles interact.
1. Bull market
A bull market is a period of sustained rising prices, often driven by strong economic growth, low unemployment, and high investor optimism. During bull markets, demand for stocks outpaces supply, and prices can rise for years. However, unchecked optimism can lead to overvaluation, creating a bubble.
2. Bear market
A bear market is the opposite: a prolonged period of falling prices, typically defined as a decline of 20% or more from recent highs. Bear markets are often triggered by economic downturns, loss of investor confidence, or the aftermath of a crash. They can last months or even years and are usually accompanied by widespread pessimism and risk aversion.
3. Stock market bubble
A bubble forms when asset prices rise rapidly to levels far above their intrinsic value, driven by exuberant buying and speculation. Bubbles are inherently unstable; when they burst, prices fall quickly and dramatically, often leading to a crash.
What are the examples of a market crash in India?
1. Global financial crisis (2008)
Triggered by a housing bubble in the US, the crisis led to approximately a 50% drop in the Indian market between 2008 and 2009. On one of the worst days, the Sensex fell by over 1,400 points.
2. Demonetisation (2016)
The sudden banning of high-value currency notes led to panic selling. The Sensex dropped by over 1,600 points and the Nifty by more than 500 points in a single day.
3. COVID-19 pandemic (2020)
As the pandemic spread and lockdowns were imposed, the Sensex crashed by 13.2%, losing nearly 4,000 points. However, the market made a swift recovery by the end of the year.
4. Crash of 2025
In early 2025, a combination of global economic concerns, foreign investor withdrawals, and domestic issues like inflation and unemployment triggered another sharp downturn. The Sensex dropped by almost 4,000 points, and the Nifty slipped below key support levels. Sectors like IT and financial services were hit hardest, and the government intervened to stabilise the market.

FAQs:
What is a market crash?
A market crash is a sudden and steep decline in stock prices across a large segment of the market, often resulting in double-digit percentage losses within days. It is usually triggered by a combination of economic shocks, panic selling, and herd behavior.
What causes a stock market crash?
Crashes are caused by factors such as excessive speculation, economic recessions, inflation, sudden tax or policy changes, panic selling, global events, and technological failures. Often, a mix of these triggers can lead to a rapid loss of confidence and mass sell-offs.
Can I profit from a market crash?
Sometimes. Some investors profit by short-selling stocks, buying put options, or investing in defensive sectors that tend to perform better during downturns. However, these strategies carry significant risk and require expertise. For most investors, the best approach is to stay disciplined, avoid panic selling, and look for long-term buying opportunities when prices are low.
Are there any measures to prevent a sudden market crash?
Regulators and exchanges have implemented measures such as circuit breakers, trading halts, and tighter margin requirements to slow down panic selling and provide time for rational decision making. While these can reduce the severity of a crash, they cannot eliminate the risk entirely.
